Wen-Szu Lin

“Chinese people are very superstitious and do not have floors for any “unlucky” numbers—that is, no numbers that include the number four (e.g., fourteen, twenty four, etc.) since “four” sounds like the word “death” in Chinese. No number thirteen either, as the country has adopted Western superstitions about unlucky thirteen. So, a building that shows fifteen floors on the floor plans physically only has twelve floors.”
